Guys. I pulled the waste gate line to run max able boost. No change. The eliminates mbc problem no????
Preload on the waste gate I'm sure if fine. I used to run 27 28 psi on 100 oct befor I got meth. I did not mess with anything other then add meth. So I'm sure its fine. But I will check and report back

You might wanna get an idea of just how much preload you are running on the WG since it won't cost you anything and just takes a minute to try.
The easiest way is to just to turn your MBC out , counterclockwise, all the way to fully soft(as far as it goes), and take it for a WOT run.

wow relax all. lol
yes the waste gate was running 15psi. wtf. so i did as sparky said and set it to as high as i can go up to 21 psi. well i can only get 18 psi out of it. but still the car is boosting wild now. my 1st log was 31 psi. ooops. i am starting my tuning on 27 psi. take it from there.
my probem was not knowing my settings on my waste gate. and not knowing out to ajust it. now i know and next time i hope to help someone else

Can you do a complete and thurough list of your mods for our info please? Neither your 10.5 hotside nor your MBC are included in the list. Do you have any other mods which aren´t listed? Is there any ECU tuning? Have you done any mods to the exhaust or the intake? Are you running the catalytic convertor and the complete factory exhaust? Do you have an air filter mod or a Walbro fuel pump?
